BALE DETACHING AND STAYING DEVICE FOR PRESSES.

SPECIFICATION forming partof Letters Patent No. 645,734, dated March 20, 1900. Application filed November 11, 1899. Serial No. 736,577. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE A. LOWRY, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Bale Detaching and Staying Device for Presses, of which the following is a specification.

This invention relates to bale detaching and staying devices for presses.

The Object of the invention is to provide means of simple construction and arrangement and which are efficient in operation for separating a length from a compressed column of material formed in or bya press sufficient I 5 to make a bale and to stay such detached-bale, as well as the end of the column from which the bale is detached, to prevent the undue expansion thereof.

Other objects of the invention will appear more fully hereinafter.

The invention consists, substantially, in the construction, combination, location, and arrangement, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.

Referring to the accompanying drawings and to the various views and reference-signs appearing thereon, Figure l is a view in longitudinal central section of a form of press, parts being broken off, showing the application thereto of a construction embodying the principles of my invention. Fig. 2 is a transverse section on the line 2 2, Fig. 1, looking in the direction of the arrows, the bale detaching and staying devices being in retracted position. Fig. 3 is a view similar to Fig. 2,

showing the bale detaching and staying devices in advanced or projected position. Fig.

4 is a broken detail view in plan of the'carrier-ring for the bale-detaching and column supporting or staying devices. Fig. 5 is a section of the same on the line 5 5, Fig. 4,

looking in'the direction of the arrows. Fig.

6 is a detached detail view in plan of the stayring upon which are supported the bale-staying devices. Fig. 7 is a view'in side elevation of the same. Fig. 8 is a broken detail view in plan of the carrier and stay-rings in assembled relation ready to be turned into position to be locked together. Fig. 9 is a view in side elevation, parts in longitudinal section, of a detached bale, showing the application thereto of the staying devices embodying the principles of my invention.

In the accompanying drawings I have shown the invention forming the subject-matter of the present application as applied to a press of the type shown, described, and claimed in my patents Nos. 581,600 and 581,601, dated April 27, 1897, and No. 630,369, dated August 8, 1899, and in some of its specific details the present invention involves certain improvements which are generically shown, described, and claimed in my pending applications, Se rial No. 725,279, filed July 27, 1899, and Se rial No. 733,174, filed October 10, 1899, A press of the type disclosed in said patents and applications and as illustrated in the accom panying drawings embodies in its general construction a slotted cap or head M and a compression chamber or holder N, these parts being mounted for relative movement. For instance, and in the particular form shown, the cap or head is stationary and the chamber or holder is revolved through suitable gearing O. In the operation of a press embodying these general features the material is fed'or otherwise suitably delivered to or adjacent to the slot or slots in the head or cap and is caught or engaged by the mass of material previously introduced into the chamber or holder and is thereby drawn into such chamber in the form of thin compressed layers or sheets from which the air has been excluded and superposed upon the mass in the chamber or holder .in spiral layers, thus building up the mass in the chamber endwise, each increment thus added correspondingly advancing the mass through the chamber or holder in the form of a highly condensed or compressed column. The present invention has particular reference to means for detaching a portion from such compressed column or mass of sufficient length to form a bale and 5 for staying such detached bale and the end of the column from which it is detached to prevent the endwise expansion thereof.

In carrying out my invention I suitably mount adjacent to the point where a bale is we to be detached a carrier-ring B-as, for instance, by securing such ring to a convenient part of the press, such as the lagging sleeve A. This ring is providedwith a peripheral flange B, through which are formed a series of passages or openings 13*. Carrier-ring B is also provided with a series of lugs or projections I), through which are formed openings or passages 1), adapted to receive the detaching and staying devices 0, which may be projected freely through said openings or passages b. Associated in operation with the carrier-ring B is a somewhat-similar ring or support D, which is provided with a series of projections or lugs D, corresponding in number with and oppositely presented with respect to the lugs or projections Z? of ring B, so that when said rings are assembled in cooperative relation the lugs or projections on the one ring will alternate with those of the other ring, the lugs or projections D projecting through the openings B in flange B. The lugs or projections D are provided with openings or passages d therethrongh, in which are arranged to freely slide the staying devices E. Lugs D are provided with projecting arms d, in which are formed grooves (1 adapted to receive pins or lugs e, formed on or carried by the staying devices E, whereby said devices are guided and held against axial rotation during the operation thereof.

I have referred to the devices 0 and E as detaching and staying devices, and said devices may be of anysuitable form adapted to perform the function of detaching a bale from the column of compressed material or of staying the detached bale or the end of the column from which the bale is detached to prevent endwise expansion thereof, or said devices may serve both functions of detaching and staying. In the drawings I have shown these devices in the form of blocks or rods having reduced or flattened ends whereby the penetration thereof into the mass of compressed material, or, more correctly, between the compressed layers com posing said column, is facilitated.

The flange B of carrier-ring B is provided with an offset or ledge 13', adjacent to one edge of each opening or passage B and which projects into said opening or passage, thereby forming a shelf or rest. Now when the rings B and D are assembled together, as shown in Fig. 8, with the lugs or projections D projecting or extending through the openings B by giving the ring or support D a slight turn or rotation in the direction of the arrow (see Fig. 8) the outer ends of the devices E when said devices are in their retracted or withdrawn position will engage over and rest upon the ofisets or ledges B thereby locking the rings 13 and D together. (See Fig. 2.) Now. when the devices E are projected, as will be presently more fully explained and as shown in Fig. 3, the ends thereof are moved clear of the ofisets or ledges B thereby effecting the disengagement of said rings from each other.

Each of the devices 0 is provided with a heel projection or lug c, forming a lateral extension which extends into position to engage the end of its adjacent and cooperating device E, whereby when said devices 0 are projected endwisethe devices E are also engaged and projected at the same time, leaving said devices E free when projected to an extent sufficient to clear the ledges or shelves 13 to be detached from the engagement of said lugs or lateral projections c. The devices 0 are also each provided with a roller or projection c, by which the said devices may be advanced or retracted.

I have shown a simple and efficient construction for securing the desired movements of the devices 0 and E and wherein I employ the levers F F, suitably pivoted intermediate their ends, as at f, upon brackets G G or other suitable or convenient part of the machine-frame. The levers F F are connected together at their ends by means of links H. The levers F F may be rocked in any suitable or convenient manner. As illustrative of one form of means for accomplishing this result I connect one end of one of the levers, as F, by means of a link H to an operating wheel or lever H, suitably pivoted upon an arm or extension G2 of bracket G or other suitable or convenient part of the frame. B rocking the operating wheel or handle H the lovers F F through links H and II will be rocked, as clearly shown in Figs. 2Vand 3. The levers F F are each provided with the flanges or projections f3, arranged when said levers are rocked in one direction or the other to engage the projections c on devices 0 and advance or withdraw them, as may be desired, the advance of said devices also-effecting the advance of devices E through the engagement therewith of the lugs or projections c. This result is secured by reason of the fact that the flanges f present their engaging surfaces in the path of the projections during the operation of the machine, it being understood that the machine is in operation when the detaching or staying devices are operated.

The stay-ring D is provided with one or more eyes D to which are secured the balestays D which, as shown, are in the form of flexible chains, as'by means of hooks cl". This connection maybe detachable, as by hinging the hooks d at d, said hook being clamped in securing position by means of a ring d By sliding the ring (1 off the end of the hook said hook may be readily released and detached from the eye D At their other ends the stays D are suitably secured to the bale base or support I, as shown in Figs. 1 and 9. In the operation of the press this bale base or support rests upon the plunger or jack J.

The operation will be fully understood from the foregoing description and is as follows: The press is started up, and the compressed column, resting upon the bale-base I and jack J, advances, said jack receding until the limit of the stays D is reached--t-hat is, in case chains or other flexible stays are employed until the slack therein is taken up. The

wheel or lever H is then operated to swing the levers F F into the position shown in Fig. 3, thereby advancing the detaching and staying devices 0 and E, the latter being advanced far enough to clear the ledges or offsets B thereby detaching a bale and also detaching the stay-ring D from the carrierring B. The jack J, which carries the detached bale, is then moved back sufficiently for the ringD to be withdrawn from ring B, and the bale, which is held clamped endwise between the ring D or the devices E,.carried thereby, and the bale base or support, is removed to receive its permanent stays. After the bale is tied the hooks d are detached and the ring D is removed, thus releasing the bale and permitting its removal from the base I. It will be observed that the devices 0 remain in their advanced position, and hence serve to hold the end of the column against endwise expansion during the operation of removing the detached bale, or until the jack J is again advanced, another stay-ring D being in the meantime applied to the carrier-ring B in the manner above described. The detaching and staying devices 0 are then withdrawn by a suitable manipulation of lever H and the compressing operation continued until it is desired to detach another bale, when the operation above described is repeated.

It is obvious that many variations and changes in the details of construction and arrangement would readily suggest themselves to persons skilled in the art and still fall within the spirit and scope of my invention. I do not desire, therefore, to be limited or restricted to the exact construction and arrangement shown and described; but,
